Warning!

To prevent short circuits, always disconnect the negative terminal

of the vehicle's electrical system before working on it.

If the vehicle has an additional battery, its negative terminal should

also be disconnected.

Warning!

Insufficient supply line connections could result in short circuits

which

– Cause cable fires

– Trigger the airbags

– Damage electronic control devices

– Cause electric functions to fail (indicators, brake light, horn,

ignition, light).

Please observe the following instructions:

z When working on the following supply lines, only use insulated cable lugs,

plugs and tab sleeves.

– 30 (direct supply from positive battery terminal),

– 15 (connected positive terminal, behind the battery),

– 31 (return line from the battery, earth).

Do not use porcelain insulating clamps.

z Use a crimping tool (see fig. 1.7, page 3) to connect the cables.

z When connecting to supply line 31 (earth)

– Screw the cable to the cable lug and gear disc to the vehicle's earth

bolt or

– With a cable lug and a self-tapping screw to the bodywork sheet metal.

Ensure that there is a good earth connection.

When the negative terminal of the battery is disconnected, all volatile

memories in the convenience electronics lose the stored data.

z The following data must be set again, depending on vehicle equipment:

– Radio code

– Vehicle clock

–Timer

– On-board computer

– Seat position

You can find instructions for making these settings in the appropriate

operating instructions.

Observe the following instructions during installation:

z Secure the parts of the MAGIC WATCH system installed in the vehicle in

such a way that they cannot become loose under any circumstances

(sudden braking, accidents) and cause injuries to the occupants of the

vehicle.

z To prevent damage, when drilling ensure that there is sufficient room for

the drill head to emerge once the hole has been made (see fig. 2, page 4).

Observe the following instructions when working with electrical parts:

z When testing the voltage in electrical cables, only use a diode test lamp

(see fig. 1.5, page 3) or a voltmeter (see fig. 1.6, page 3).

Test lamps with an illuminant (see fig. 1.9, page 3) take up voltages which

are too high and which can damage the vehicle's electronic system.

z When making electrical connections, ensure that

– They are not kinked or twisted

– They do not rub on edges

– They are not laid in sharp edged ducts without protection (see fig. 3,

page 4).

z Insulate all connections.

z Secure the cables against mechanical wear with cable binders or insulat-

ing tape, for example to existing cables.

Please observe the following instructions in particular:

z Installing the reversing distance sensor can cause problems on vehicles

with LED tail lights.

Please consult the manufacturer of your vehicle.

z Whenever possible, do not mount the sensors directly above the end of

the exhaust. Otherwise errors in the display may result.

z Observe the applicable legal regulations.

z The sensors may not cover signal lamps.

z When reversing, make sure no other road users can be injured.

z Physical reflection properties mean you may not be able to recognise

critical obstacles.

z MAGIC WATCH is designed merely as an additional aid, which means it

does not release you of the duty of taking due care when reversing.

z MAGIC WATCH can only provide a warning in time if you reverse slowly

(at parking speed).

z Remove any snow, ice or dirt from the sensors so that the function is not

impaired.

4 Proper use

MAGIC WATCH is an ultrasonic reverse warning system. When reversing, it

monitors the space behind the vehicle and provides an audible and visible

warning signal for any obstacles it detects.

Since MAGIC WATCH is designed merely as an additional aid for reversing,

it does not relieve you of the duty to take proper care when reversing.

MAGIC WATCH is designed for installation in cars.

5 Technical description

5.1 Functional description

MAGIC WATCH consists of three built-in sensors, a controller, a display for

visual warning signals, and a piezoelectronicspeaker for audible warning sig-

nals. The piezoelectronic speaker is fitted on the parcel shelf or boot cover.

The display can be mounted on the dashboard, on the rear view mirror, on

the windscreen or on the boot cover.

It measures distances based on the echo time principle. The three sensors

constantly emit ultrasonic signals when you reverse.

The sensors contain both transmitters and receivers, and capture any ultra-

sonic signals reflected by obstacles. The distance to the obstacle is calcu-

lated using the echo time, and signalled by the speaker using a sequence of

impulse tones. The closer the obstacle approaches, the faster the succes-

sion of warning tones.

The display signals the position of the obstacle using three LEDs. A numeri-

cal display shows the distance:

z in 10 cm increments if the distance to the obstacle is more than 1 metre

z in 2 cm increments if the distance to the obstacle is less than 1 metre

The sensors are installed on the bumper. It is possible to paint the sensors,

but not with a multicoat paint, as it impairs the functionality of the sensors.

Since the sensors are equipped with their own amplifiers, you can extend the

connection between the sensors and the controller to up to 20 m.

MWE-250-3DIS.book Seite 34 Mittwoch, 6. Juli 2005 4:34 16

magic watch Technical description

35

Only use WAECO cables (MWSC-1).

Otherwise, proper operation cannot be guaranteed.

Defective sensors can be replaced without removing the bumper. There is a

plug connector just behind the sensor for this.

5.2 Detection range

The detection range of MAGIC WATCH is divided into three zones (see fig. 5,

page 5):

z Zone 1

This zone is the first limit range. Small or objects with poor reflective char-

acteristics are sometimes not detected in this zone.

z Zone 2

Nearly all objects are displayed in this zone.

z Zone 3

Nearly all objects are displayed in this zone, but some objects may come

into the blind spot of the sensors.

Situations may arise where MAGIC WATCH does not detect

objects or fails to signal their distance correctly, due to their physi-

cal characteristics.

Note the four following examples.

Example 1 (see fig. 6, page 5)

Objects which do not enter the detection area of the sensors cannot be

recorded.

Example 2 (see fig. 7, page 5)

The distance to objects with large gaps in them may not be correctly sig-

nalled. In the example, A is not signalled, but only B or C instead.

Example 3 (see fig. 8, page 5)

For diagonal obstacles, the shortest distance A is signalled.

MWE-250-3DIS.book Seite 35 Mittwoch, 6. Juli 2005 4:34 16

Technical description magic watch

36

Example 4 (see fig. 9, page 6)

In this case, MAGIC WATCH displays the distance A. As the vehicle

approaches the audible indicator goes over to the stop zone, and as it

approaches further, the distance A goes into the blind spot, so that MAGIC

WATCH signals the distance from point B.

Caution!

As these four examples show, situations can arise where the

device fails to display an object or does not display the shortest

distance.

The device does not relieve you of your obligation to take special

care when reversing. Therefore, always be extremely careful

when reversing.

If an object enters the blind spot of the sensors, MAGIC WATCH

automatically shows the distance to the next object. This means

the speaker changes from fast to medium beeps and the numerical

display shows a different distance.

In this case, always stop the vehicle immediately and check the

situation.

6 Installing MAGIC WATCH

6.1 Tools required

For installation and assembly you require the following tools:

z Drill bit set (see fig. 1.1, page 3)

z Drill (see fig. 1.2, page 3)

z Screwdriver (see fig. 1.3, page 3)

z Set of ring or open-ended spanners (see fig. 1.4, page 3)

For making and testing the electrical connection the following tools are

required:

z Diode test lamp (see fig. 1.5, page 3) or Voltmeter (see fig. 1.6, page 3)

z Crimping tool (see fig. 1.7, page 3)

z Insulating tape (see fig. 1.8, page 3)

z Cable bushing sleeves, if required

To secure the controller and the cable you may require additional screws

and cable binders.

6.2 Fitting the sensors

The sensors must be correctly aligned for the device to work.

If these point to the ground, bumps in the ground may be inter-

preted as obstacles. If they point too far up, obstacles will not be

detected.

Note the following information during installation:

z The maximum range is approximately 1.5 m.

z So that the corners of the vehicle (indicator lights etc.) can be monitored,

the sensor should not be fitted more than 0.3 m away from them.

z The distance from the sensors to the ground must be between 40 cm and

50 cm (see fig. 10, page 6).

MWE-250-3DIS.book Seite 37 Mittwoch, 6. Juli 2005 4:34 16

Installing MAGIC WATCH magic watch

38

z The installation location should be as flat as possible so that the cover ring

of the sensor is on the bumper.

The sensor is preset to have a vertical installation angle of

approximately +5°. This means that the cover ring is thicker at the bot-

tom.

Note that the sensors must be aligned in a particular direction. The top of

the sensor is marked with a ▼ (see fig. 11.1, page 6).

z It is possible to paint the sensors, but not with a multicoat paint, as it

impairs the functionality of the sensors.

The installation procedure is as follows:

➤ Choose an installation location on the bumper which is as perpendicular

to the road surface as possible (see fig. 11, page 6).

Caution!

Before making any drill holes, ensure that no electrical cables or

other parts of the vehicle can be damaged by drilling, sawing and

filing.

➤ For each sensor, drill a hole with a diameter of 22 mm in the bumper.

➤ For a more accurate fit, slant the drill downwards slightly when drilling the

hole on the inside of the bumper. The sensor cover can now be easily

inserted at a downward angle.

➤ Guide the cables of the sensors through the corresponding hole.

➤ Insert each sensor into the corresponding drill hole until it latches into

place.

6.3 Laying the sensor extension cables

When laying cables, ensure that:

z They are not kinked or twisted

z They do not rub on edges

z They are not laid in sharp edged ducts without protection (see fig. 3,

page 4).

z The plugs must be connected with the correct polarity. A blocking pin pre-

vents reverse polarity (see fig. 12 A, page 6).

z Make sure the locking pin catches (see fig. 12 A, page 6). Only then is

trouble-free operation guaranteed.

To release the connection press the holder and pull the plug and socket

apart (see fig. 12 B, page 6).

z If the sensor cable is not long enough, you can order one-metre extension

cables (MWCD-1) as accessories.

Note

The extension cables are marked: L (left) and R (right).

This marking helps you connect them to the control electronics to

ensure that the display is correct.

Caution!

Before making any drill holes, ensure that no electrical cables or

other parts of the vehicle can be damaged by drilling, sawing and

filing.

➤ Take suitable precautions to protect holes made in the bodywork from

water penetration, for example by spraying the cable and the sleeve with

sealant.

➤ Where possible, use existing rubber bungs in the boot for laying the

extension cables.

If there are no rubber bungs, make a suitable hole with a diameter of

around 13 mm and insert a cable sleeve.

Note

Pull the socket connectors of the extension cables through the

cable sleeve before inserting the sleeve in the body work.

➤ Lay out the extension cables in the boot so that they cannot be damaged

under any circumstances (e.g. by flying grit).

➤ Carefully fasten the extension cables behind the bumper.

➤ Insert the sensor plugs into the sockets of the corresponding extension

cables (see fig. 15 A, page 8).

6.4 Fastening the control electronics

Note the following information when selecting a place to fit the control elec-

tronics:

z Note the length of the sensor cables.

z The control electronics may not be damaged if you have luggage or

objects in the boot.

➤ Fasten the control electronics to a suitable place in the boot.

The control electronics should not be exposed to any moisture.

Note

The extension cables are marked: L (left) and R (right).

This marking helps you connect them to the control electronics to

ensure that the display is correct. These markings can also be

found on the control electronics.

The polarity of the socket cannot be reversed: They can be only

be plugged into the connection in one way.

➤ Plug the sockets of the sensor cables into the connections on the control

electronics (see fig. 15 B, page 8).

Make sure the locking pin catches.
